node-git-tools

Tools for parsing data out of git repositories.

About

The goal of node-git-tools is to provide a set of tools that can be used to easily write custom git commands or other scripts that are tightly integrated with git.

I expect the API to grow over time and will happily entertain any feature requests. If there is anything you'd like added, just file an issue.

Installation

npm install git-tools

Usage

var Repo = require( "git-tools" );
var repo = new Repo( "path/to/repo" );
repo.authors(function( error, authors ) {
	console.log( authors );
});

API

Repo.clone( options, callback )

Clones a repository and returns the new Repo instance.

• options (Object): Options for cloning the repository.
  • repo (String): The repository to clone from.
  • path (String): The path to clone into.
  • extra: Additional options can be provided, as documented below.
• callback (Function; function( error, repo )): Function to invoke after cloning the repository.
  • repo (Object): A new Repo instance for the cloned repository.

This function accepts arbitrary options to pass to git clone. For example, to create a bare repository:

Repo.clone({
	repo: "git://github.com/scottgonzalez/node-git-tools.git",
	dir: "/tmp/git-tools",
	bare: true
});

Or to create a repo with limited history:

Repo.clone({
	repo: "git://github.com/scottgonzalez/node-git-tools.git",
	dir: "/tmp/git-tools",
	depth: 5
});

Repo.isRepo( path, callback )

Determines if the specified path is a git repository.

• path (String): The path to check.
• callback (Function; function( error, isRepo )): Function to invoke after determining if the path is a git repository.
  • isRepo (Boolean): Whether the path is a git repository.

Note: This is equivalent to creating a Repo instance with path and calling isRepo() on the instance.

activeDays( [committish], callback )

Gets the number of active days (unique days of authorship). Includes activity by day, month, year, and the entire history.

• committish (String; default: "master"): Committish range to analyze.
• callback (Function; function( error, activeDays )): Function to invoke after getting active days.
  • activeDays (Object): Summary of active days.

The activeDays object has the following form:

{
	activeDays: Number,
	commits: Number,
	dates: {
		"YYYY-MM-DD": Number( commits ),
		...
	},
	years: {
		"YYYY": {
			activeDays: Number,
			commits: Number,
			months: {
				"M": {
					activeDays: Number,
					commits: Number,
					days: {
						"D": {
							commits: Number
						},
						...
					}
				},
				...
			}
		},
		...
	}
}

age( callback )

Gets the age of the repository.

• callback (Function; function( error, age )): Function to invoke after getting the age.
  • age (String): The age of the repository.

authors( [committish], callback )

Gets all authors, sorted by number of commits.

• committish (String; default: "master"): Committish range to analyze.
• callback (Function; function( error, authors )): Function to invoke after getting authors.
  • authors (Array): All authors, sorted by number of commits.

Each author object contains the following properties:

• email (String): Author's email address.
• name (String): Author's name.
• commits (Number): Number of commits.
• commitsPercent (Number): Percentage of commits.

blame( options, callback )

Determine what revision and author last modified each line of a file.

• options (Object): Options for the blame.
  • path (String): The path to the file to run the blame for.
  • committish (String; default: "HEAD"): Revision or range to blame against.
• callback (Function; function( error, blame )): Function to invoke after blaming the file.
  • blame (Array): Commit information for each line.

Each blame item contains the following properties:

• commit: SHA of commit that most recently modified the line.
• path: Path to the file at the time of the most recent modification to the line.
• lineNumber: Line number within the file.
• content: Contents of the line.

branches( callback )

Gets all branches in order of most recent commit.

• callback (Function; function( error, branches )): Function to invoke after getting branches.
  • branches (Array): All branches, sorted by most recent commit date.

Each branch object contains the following properties:

• name (String): Branch name.
• sha (String): SHA-1 of most recent commit.
• date (Date): Author date of most recent commit.
• subject (String): Subject (first line) of most recent commit.
• author (Object): Author of most recent commit.
  • email (String): Author's email address.
  • name (String): Author's name.

config( name, callback )

Gets the value of a configuration option.

• name (String): The name of the configuration option.
• callback (Function; function( error, value )): Function to invoke after getting the configuration option.
  • value (String|null): The value for the configuration option, or null if no value is set.

currentBranch( callback )

Gets the name of the currently checked out branch, if any.

• callback (Function; function( error, branch )): Function to invoke after getting the branch.
  • branch (String|null): Branch name, or null if in detached HEAD state.

isRepo( callback )

Determines if the specified path is a git repository.

• callback (Function; function( error, isRepo )): Function to invoke after determining if the path is a git repository.
  • isRepo (Boolean): Whether the path is a git repository.

remotes( callback )

Gets all remote repositories.

• callback (Function; function( error, remotes )): Function to invoke after getting the remotes.
  • remotes (Array): All remote repositories.

Each remote object contains the following properties:

• name (String): Remote name.
• url (String): URL for the remote repository.

tags( callback )

Gets all tags in reverse chronological order.

Lightweight tags are sorted by author date and annotated tags are sorted by tagger date.

• callback (Function; function( error, tags )): Function to invoke after getting tags.
  • tags (Array): All tags, sorted by date.

Each tag object contains the following properties:

• name (String): Tag name.
• sha (String): SHA-1 for the tag. For lightweight tags, this is the SHA-1 of the commit.
• date (Date): Author date for ligthweight tags, tagger date for annotated tags.
